Since nobody answered your question I'll give it a try by asking a few of my own.

What are your goals with a programmer? What do you want to achieve?

Maybe a slight bit more power/economy...nothing high HP. I had talked to my local mech at Ram dealer and he said another customer had one and was very pleased with the economy and the added power/economy for towing and they aren't too expensive. As for warranty issues, he said chyr would have to prove the programmer directly caused whatever failure if something happened.

IB pretty much answered your question.
To add to it. Can a tuner give you economy? Well yes, sometimes.

A tuner plays with about 3 different major things. Injection timing fuel quantity and boost pressure.

Advancing injection timing will make your engine more efficient so you can pick up a "slight" bit of mileage if you drive your truck lightly.

Fuel quantity kills off the economy. To add power you need to add fuel. So if you use that power you will use more fuel. IOW's a 200 HP diesel will use about twice the fuel as a 100 HP diesel. So if you only had 375 HP and use all that power to pull a hill at 40 MPH and then you add a tuner to give you 450 HP and you now go up the same hill at 55 MPH you will use a LOT more fuel. You have to because you just added 75 HP worth of fuel.

Turbo boost does not really do much for or against fuel economy. It's just there to cool things off and keep things clean.

Let me caution you that the 6.7 is wound pretty tight. In other words it's pretty much at it's limit to make more power without beefing up other parts. Even the DPF is built to handle a certain amount of fuel. You raise that amount and bad things can happen.

As far as warrantee goes, IB is spot on. If you break something in the drive train they will just deny your repair. You will tell them they can't do that and they will tell you yes they can. You have a broken truck and they lose nothing. Take them to court? Good luck. Hope you have a long time and a lot of money. Even then you will lose because it says right in the OM a tuner will void warrantee.

In the end it's up to you whether its worth it to add a tuner.
